One of the objects of" this. invention is to provide a burner with antimprovedsupporting base which may be individually adjustable for each of the burner. units. 1 1

Another object of the invention isthe provision of an inlet opening located out of registry withthe conduit connecting two of the annular fuel chambers. 1

Another object of the invention is the provision of a brace plate extending across=the burner-{to support the fuel chambers and reinforce the inlet opening... t a Another object of the invention is .the provision of a brace plate" which cooperates with the support standard for mounting the burner thereon. w I further object of the invention is the-provision of a preheatingreservoir which may be swung from beneaththe fuel chambers for the reception of preheating fuel. t I

A still further object of the invention is the utilization of the connections. between the annu lar fuel chambers as axmeans for conducting fuel from one to the'other; Y

With these and other objectsin view, th m-i vention consists of certain novel features of construction, as will be more fully -des'c.ribed,. and

particularly pointed out in the appended claims. '1

It has been found desirable in theuse. of range oil burners to provide a supportfor the individual units which may be readily adjustable to locate the burner at the desired height. It is also desirable to provide a construction which will minimize the carbon deposit, and a construction by. which the burner may be preheated for ignition without using wicks; and this is accomplished opening so that it will beat a point spaced from and 'I have provided preheating troughs beneath each of these brace members 18 for'connecting the annular'chambers 16v and 1'7, so that fuel 23 to hold the standard in adjusted position. This standard may be of any desired height to .of thebrace plate there is provided an inlet opening 24 connected to the innerannular chamber through a long range whichi m ay be adjusted at the desired height. Ihave'arrang'ed'an inlet theconnection between the annular chambers;

the burner toswing therefrom for the'reception [Of fuel for preheating. I have also provided the brace plate in such a manner as to support the burner andstrengthenthe inlet opening as well as permit the supportstandard therefor to extend v therethrough, a considerable. extent where I a wider rangeof'vertical adjustment may be accomplished; and the following is a detailed description of'the present embodimentof this .in

vention; illustrating 'the preferred means. ,by which theseadvantageous results may beaccomplishedf k With 'reference to the drawing, 10 designates V the burner basewhich isgenerallytriangular shape'and provided with bolts 11 extending there through to form adjustable'feetfor the base. to' level the same on the bottom of the stove or other support 'upon which it may be located. An opening 12 is provided inthe base'and a collar 13 extends upwardly therefrom for the reception of a support standard 14 which is heldin adjusted position in the collar andv base by means of a setscrewl5;

The burner consists of a cast body providing an inner annular chamber 16 and an outer'annu- 35 lar chamber 17 with bridge members 18 extendpoints for connecting them together, and I utilize the brace members to provide. conduits 19 through may flow through'the conduits 19 from one cham berto' the other. Abrace plate 20 extends diametrically ac'rossthe inner annular chamber; and is provided with an opening 21 from which there extends a collar 22 for the reception of thesupport standard l4 which extends through" the collar and opening and is held therein by a set screw project through the opening 21 and collar 22 to, provide along range of adjustment.

. The brace member 20 is located out of line with l the opposite bridge members 18 and at one end -1O5 16 for the supply of fuer thereto through the conduit25 which includes suitable sediment trap267 provided at itsend. The fuel opening 24 is thus located intermediate two of 'the conduits 19- and 2 2 5 7 I l f is substantially midway therebetween, and I find that by this arrangement less carbon is formed in the use of the burner than where the inlet opening is located closely adjacent one of the conduits between the annular chambers.

It will be understood that in use, perforated cylindrical members rest upon the shoulders 2'7 on either side of each of the annular chambers to provide combustion chambers and assist in the burning of the oil, all of which is customary and Well known.

The oil which burns after the burner is heated, burns as a gas, although in order that the burner may be started, it is usually necessary to provide a wick projecting from the fuel chambers; but in order that a wick may be eliminated, I have provided a pair of preheating troughs 28 and 29, hav,

ing lug portions offset in different vertical planes,

as shown in section in Figure 4, these lug portions being pivoted on the post 30 secured to the brace member 20. These troughs are arcuate in shape and extend horizontally in a unilateral plan due to the provision of the above mentioned offset portions and they fit beneath the burner so that the fuel therein when ignited will heat the burner for the'starting of the same. It will benoted by referring to Figures 3 and 4 of the accompanying drawing thatwhen the preheating troughs are in operative position they extend entirely within the periphery of the burner proper for the reason that the transverse dimension of the troughs is substantially equal to the transverse dimension of the burner. These troughs are each usually provided with'a filling of asbestos to assist in the burning of the oil and each may be swung from beneath the burner on the pivot 30 to expose the same for loading with fuel prior to ignition.

I have illustrated two of such preheating troughs or reservoirs, although I find in many instances it is necessary to use but one by which construction I eliminate the use of wicks in'the burner.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I'claim:

. 5. A device of the'character described, comprisinga ring-shaped fuel burner, a brace member therefor, a support for said burner extending through said brace member, a pair of arc-shaped troughs having a transverse dimension'substantially equal to the transverse dimension of said burner; and the combined'length of said troughs approximating the circumferentialdimension of said burner, and a single means carried by said brace member for pivotally mounting said troughs in a unilateral plane beneath said burner whereby said troughs will align with the peripheral walls of said burner in one positionand also being capable of swinging, outwardly beyond the outer periphery of the burner. j
